.TH FILELUOPEN 3 "15. Juli 1988" "J\*org Schilling" "Schily\'s LIBRARY FUNCTIONS"
.SH NAME
fileluopen() \- opens a file given a logical unit number
.SH SYNOPSIS
.nf
.B
FILE *fileluopen(lu, modes)
.B	int lu;
.B	char *modes;
.fi
.SH DESCRIPTION
fileluopen() makes an object of type FILE, suitable for use with
fileread(), putc(), etc.
.PP
The lu argument is a logical unit number assigned by the kernel
when it opens a file. Logical unit numbers are not usually
visible, although several routines reguire LUs as
arguments and fdown() may be used to map a FILE object to a
corresponding LU number.
.PP
The modes argument is a string encoding the modes of the file,
just as for fileopen(), except that the 'c' and 't' options are
not allowed.
.SH RETURNS
Returns the FILE value.
.SH NOTES
none
